Here’s what Rumi says:
Through love bitter things seem sweet.
Through love scraps of copper are turned to gold.
Through love agonies are healing balms.
Through love thorns become roses.
Through love vinegar becomes rich wine.
Through love the scaffold becomes a throne.
Through love disaster becomes good fortune.
Through love a prison becomes a rose garden.
Through love burning fire is a fragrant light.
Through love the devil becomes an angel.
Through love stones become soft as butter.
Through love grief is like delight.
Through love demons become servants of God.
Through love stings are like honey.
Through love lions are harmless as mice.
Through love sickness is health.
Through love the dead are resurrected.
Through love the emperor becomes a slave.
